Computerized physician-order entry: are we there yet?

Computerized physician-order entry (CPOE) is a system of hardware and software through which a physician enters orders directly into a computer rather than writing them on paper. The advantages of CPOE include order legibility, improved response time, reduction in adverse drug reactions, reduced cost of care, and improved patient outcomes. The maturation of mobile computing platforms, graphical user interfaces, and wireless technologies are making CPOE more practical for both outpatient and inpatient care. Significant barriers to the implementation of CPOE include the reluctance of physicians to change existing practices, doubt about the possible benefits, increased front-end time to enter orders, and system cost.
